Definitions

  • the present invention relates to a protective structure for rows of plants as defined in the preamble of claim 1, in particular a protective structure for protecting fruit trees from atmospheric phenomena such as hail, as well as from overexposure to the sun, insects and the like.
  • fruit trees are arranged in parallel rows which are suitably spaced apart to allow the passage of people walking or agricultural machines.
  • These rows extend to a length of many meters, for example even to 50 or 100 meters, and the fruit trees are pruned and grown while maintaining the spacing between rows.
  • Fruit trees should be provided with a protective structure to preserve the production of fruits from possible hailstorms, i.e. from atmospheric conditions that tend to occur just when the fruits are ripe or ripening.
  • a hailstorm may apparently cause considerable damage, because it can cause the ripening fruits to fall or can bruise them and make them unsuitable for sale.
  • anti-hail nets have been widely used to cover fruit trees and protect them from hail.
  • US 2017/238477 A1 relates to an automated rolling greenhouse cover comprising an upper current from which two motorized side rolling covers, i.e. left and right covers, roll down onto the supporting structure of a greenhouse. Therefore, the cover necessarily requires the provision of a greenhouse supporting structure which extends along the entire row and obstructs the passage between two rows of crops.
